New Zealand First MP Shane Jones says moving the Ports of Auckland to the Manukau harbour would go against 200 years of shipping expertise.
A new report published yesterday recommends moving the port to Manukau or the Firth of Thames.
An earlier report New Zealand First backs identified Northport at Marsden Point as the best option.
Auckland Mayor Phil Goff has called the previous Northport work 'shoddy' and Transport Minister Phil Twyford has aligned himself with Goff.
New Zealand First stands by the previous report that recommends the Northland option.
Jones speaks to Kim Hill.
